DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0030] The present application relates to a kind of down lamp mounting structure, including lamp shell 100, connecting seat 200 and elastic sheet 300.

[0031] As shown in Figure 1 , Figure 2 , Figure 3 And Figure 4 , the shape of lamp shell 100 is not limited, can be cylindrical, disc-shaped etc.. Lamp cap 400 is installed in lamp shell 100, the structure of lamp cap 400 is not limited, such as Figure 7 ,​​​​​Figure 8 and Figure 9 As shown in the figure, the lamp head 400 can be single-beam irradiation, or multi-beam irradiation, etc. The lamp shell 100 is provided with a boss 110. The connecting seat 200 is provided with a notch 210. In the embodiment, the connecting seat 200 is provided in a disc shape. In the direction of the figure, the axial direction of the connecting seat 200 is the vertical direction, and the radial direction is the horizontal direction. The notch 210 is recessed inward along the radial direction on the peripheral wall of the connecting seat 200. The notch 210 is provided with a support platform 220, and the height dimension of the support platform 220 in the axial direction of the connecting seat 200 is smaller than the height dimension of the notch 210, and the support platform 220 is located at the lower part of the notch 210. During installation, the connecting seat 200 can be fixed on the ceiling, and then the lamp shell 100 is moved from below to above to approach the connecting seat 200. When the lamp shell 100 is moved upward, the boss 110 is inserted into the notch 210 from below to above, and then the lamp shell 100 is translated or rotated, the boss 110 is moved above the support platform 220, the boss 110 is lapped on the support platform 220, and the support platform 220 clamps the boss 110 in cooperation with the ceiling, or the boss 110 clamps the support platform 220 in cooperation with other components inside the lamp shell 100. The elastic sheet 300 is installed on one of the boss 110 and the support platform 220, that is, the elastic sheet 300 is installed on the boss 110, or the elastic sheet 300 is installed on the support platform 220, or the elastic sheet 300 can be installed on both the boss 110 and the support platform 220. In the embodiment, the elastic sheet 300 is installed on the support platform 220, and the elastic sheet 300 protrudes upward from the support platform 220. When the boss 110 is lapped on the support platform 220, the elastic sheet 300 abuts against the bottom of the boss 110 upward, and the elastic sheet 300 pokes the boss 110 to be elastically supported upward, so that the clamping force of the support platform 220 on the boss 110 in cooperation with the ceiling or the clamping force of the boss 110 on the support platform 220 in cooperation with other components inside the lamp shell 100 is larger. The elastic expansion and contraction of the elastic sheet 300 replaces the clamping gap in the axial direction during installation, so as to ensure that the lamp shell 100 and the connecting seat 200 will not easily shake and separate from each other due to the clamping gap in the axial direction, and the boss 110 and the support platform 220 do not need to be provided in an interference fit, so as to avoid the difficulty in installation and removal.

[0032] In one embodiment, the elastic sheet 300 is mounted on one of the boss 110 and the support base 220, and the other is provided with the groove 120. In this example, the elastic sheet 300 is mounted on the support base 220, and the groove 120 is provided on the lower side of the boss 110. The groove 120 is concave upward. When mounted, the elastic sheet 300 slides into and is clamped in the groove 120 as the boss 110 and the support base 220 move relatively, thereby further improving the mounting stability of the lamp housing 100 and the connecting seat 200, and the lamp housing 100 and the connecting seat 200 will not move relatively under the action of a large external force. When disassembled, the lamp housing 100 is moved, the elastic sheet 300 slides out of the groove 120, and then the lamp housing 100 can be disassembled from the connecting seat 200.

[0033] Based on any of the above embodiments, as shown in Figure 4 、 Figure 5 and Figure 6 , the support base 220 has opposite first and second side surfaces 221 and 222. In the direction shown, the upper side of the support base 220 is the first side surface 221, and the lower side is the second side surface 222. The support base 220 is provided with a through hole 223, which penetrates the first and second side surfaces 221 and 222. The elastic sheet 300 includes an elastic pressing portion 310. The elastic sheet 300 is mounted on the second side surface 222, and the elastic pressing portion 310 passes through the through hole 223 upward from the second side surface 222, and the elastic pressing portion 310 can elastically protrude upward beyond the first side surface 221. Under the action of other external forces, the elastic pressing portion 310 remains in the state of protruding beyond the first side surface 221. When the boss 110 is lapped on the first side surface 221, the elastic pressing portion 310 is elastically retracted downward under the pressure of the boss.

[0034] Further, the elastic sheet 300 can be a metal sheet with a certain elastic deformation force. As shown in Figure 5 and Figure 6 , the elastic sheet 300 further includes a first sheet portion 320, a second sheet portion 330, and a clamping portion 340. The elastic pressing portion 310 can be provided in the shape of an inverted V, an inverted U, or other shapes. The first and second sheet portions 320 and 330 extend from the two sides of the elastic pressing portion 310, respectively. The clamping portion 340 extends from the side of the second sheet portion 330 away from the elastic pressing portion 310. The second side surface 222 is provided with a clamping groove 230. The clamping groove 230 opens downward. The clamping portion 340 is inserted into and clamped in the clamping groove 230 from above. The first and second sheet portions 320 and 330 are located on the lower side of the second side surface 222. The elastic pressing portion 310 moves up and down elastically with the second sheet portion 330 clamping the clamping portion 340, and the second side surface 222 limits the upward travel of the first sheet portion 320. At the same time, the first sheet portion 320 is used to limit the upward position of the elastic pressing portion 310 relative to the through hole 223, so as to avoid the elastic pressing portion 310 from being stuck in the through hole 223 when it is subjected to sliding friction of the boss 110.

[0035] Based on the above embodiment, the clamping portion 340 includes a third piece portion 341 and a fourth piece portion 342. The third piece portion 341 extends from the second piece portion 330. The fourth piece portion 342 is bent from the third piece portion 341. The fourth piece portion 342 and the third piece portion 341 are inverted V-shaped or inverted U-shaped. The third piece portion 341 and the fourth piece portion 342 tend to elastically deform relatively away from each other, that is, the third piece portion 341 and the fourth piece portion 342 tend to relatively open under the action of their own elasticity. The third piece portion 341 and the fourth piece portion 342 abut on the two side walls of the clamping groove 230, respectively, and the relative elastic force of the third piece portion 341 and the fourth piece portion 342 causes the clamping portion 340 to be fixed in the clamping groove 230. The lower side of the fourth piece portion 342 abuts on the groove wall of the clamping groove 230, further limiting the clamping portion 340 from disengaging from the clamping groove 230 during use. Among them, the groove wall of the clamping groove 230 abutted by the fourth piece portion 342 is defined as the mounting wall 231. A through groove 232 can be formed on the mounting wall 231, which penetrates the mounting wall 231 along the thickness direction of the mounting wall 231. Through the through groove 232, it can be directly observed whether the clamping portion 340 is installed in place in the clamping groove 230. In addition, when it is necessary to disassemble the elastic sheet 300, a tool can be used to abut on the fourth piece portion 342 through the through groove 232, and then press the fourth piece portion 342 to move towards the third piece portion 341, so that the clamping portion 340 quickly disengages downward from the clamping groove 230, avoiding damage to the elastic sheet 300 due to the clamping portion 340 being clamped too tightly during disassembly.

[0036] In an embodiment, as shown in Figure 1 and Figure 2 The lamp shell 100 is provided with a mounting port 130. The mounting port 130 is formed at the upper end of the lamp shell 100. The boss 110 is arranged on the inner wall of the mounting port 130. The shape of the connecting seat 200 is matched with the shape of the mounting port 130. During installation, the lamp shell 100 is moved upward to approach the connecting seat 200, the connecting seat 200 is inserted into the mounting port 130, and then the lamp shell 100 is rotated, the mounting port 130 and the connecting seat 200 are relatively rotated, and then the boss 110 is slid into the upper side of the support table 220.

[0037] Among them, the connecting seat 200 is provided with at least two notched positions 210. The notched positions 210 are sequentially distributed along the circumference of the connecting seat 200. The lamp shell 100 is provided with at least two bosses 110, which are sequentially distributed along the axial direction of the mounting port 130. Each notched position 210 is provided with a support table 220. The number of bosses 110 and notched positions 210 is the same and one-to-one matched in position, and the boss 110 and the notched position 210 are one-to-one matched and slid. Through the cooperation of the at least two groups of bosses 110 and support tables 220, the installation stability is improved.
